Test Report T64-3-
1. U.S. Army Frankford Arsenal, Philadelphia, Pa., USA, 1963. – 20 p.This study was conducted to determine the adequacy of the rotating band, particularly band retention, of the standard 155mm M107 shell when fired with propelling charge XM119 from the 155mm Howitzer Self-Propelled M109 (T196E1). Rotating bands from sixteen recovered Ml07 shell were examined.
The bands imparted full spin to the projectile, but showed varying amounts of wear proportional to the pressure and velocity level. This amount of wear did not adversely affect the velocity or range dispersions. Band fly off was primarily attributed to poor banding practice and lack of band seat undercuts. If the percentage of band fly off warrants rebanding, widening of the band seat and inclusion of 15° band seat undercuts is recommended.Contents:
